Guang Zong and his twin brother, Yao Zu were very close to each other. They were sent to an orphanage by their grandfather, who could not take care of them financially, after the death of their parents.

One day, a married couple came to the orphanage to adopt a child. They liked Guang Zong, but not the other twin, Yao Zu. Subsequently, the twins were separated. To enable them to meet again, they promised each other to play badminton well, so that they could enrol themselves in the same sports school.

After Guang Zong left, Yao Zu went back to his grandfather. He trained very hard in badminton and thought Guang Zong would also do the same.Meanwhile, Guang Zong's adoptive parents were very strict with him. Under tremendous pressure, he ran away from home but was soon found. As a result, he became an introvert and spent most of his time playing piano, in his own room.

Slowly, Guang Zong fell in love with the piano and wanted to be a musician and lost his interest in badminton...

Would the promise between the twins be kept? How to choose between family love and ambition?
